Basic screen 32 bit - works with scalers
Fixed standard scale function - other scalers seem to work ok
More elegant way to get default zoom method working
First 32 bit surface - globe. Shading doesn't work
Some palette removing stuff
Preparation for 32bit shader
Battlescape starts, but display isn't working (more shading problems)
Reverted most surfaces to 8bpp
Merge remote branch 'upstream/master' into 32bit_Surface_Support
Merge remote branch 'Yankes_remote/ShaderDraw32bit' into 32bit_Surface_Support
